Performance Features:

HL-320 is a new type of PVC impact modifier independently developed by our company. The interpenetrating network copolymer formed by grafting of light chlorinated HDPE and acrylate overcomes the shortcomings of high glass transition temperature and poor dispersion of CPE, which can provide better toughness, low temperature impact resistance and improve weather resistance. It is mainly used in PVC pipes, profiles, boards, and foamed products.

·Completely replacing ACR, CPE and ACM (recommended dosage is 70%-80% of the dosage of CPE).
·Excellent compatibility with PVC resins and good thermal stability, reducing melt viscosity and plasticizing time.

·According to the change of current and torque, the amount of lubricant can be reduced properly
·Greatly improving hardness and weatherability of PVC pipes, cables, casings, profiles, sheets, etc.
·Providing better tensile strength, impact resistance and elongation at break than CPE.

Packaging and Storing:
Compound paper bag: 25kg/bag, kept under seal in a dry and shady spot.
